The future of computing may lie not in electrons, but in photons – that is, in microprocessors that use light instead of electrical signals. But these so-called photonic devices are typically built using ...

(Phys.org) —DNA damage is a fact of life. On any given day, an organism's DNA will suffer between 10,000 and 1,000,000 breaks or other damage. These problems are repaired by enzymes in our cells that fix ...

A silicon-based laser that lases up to a record 111°C, with a threshold current density of 200 A/cm2 and an output power exceeding 100 mW at room temperature, has been demonstrated by collaborating researcher ...

An international team directed by researchers from the Austrian Academy of Sciences, with participation from the Universitat Autònoma de Barcelona, has managed to create an entanglement of 103 dimensions with only two photons. ...

A simple method to sense DNA, as well as potential biomarker proteins of cancer or other diseases such as Alzheimer's, may soon be within reach - thanks to the work of a team of Yokohama National University ...

A large team of researchers with members from MIT, IBM, NASA's JPL and Columbia University has developed a process that that enables scalable integration of superconducting nanowire single-photon detectors ...

Light is of fundamental importance. It allows us to see the world around us and record pictures of our environment. It enables communication over long distances through optical fibers. All current methods ...

(Phys.org) —A team of physicists working at the University of Erlangen-Nuernberg in Germany has built a working optical diametric drive. In their paper published in Nature Physics, the team describes how th ...

As members of the LHCb collaboration, scientists at EPFL have analyzed data collected at CERN's Large Hadron Collider that offer a first-time observation of the polarization of the photon emitted in the weak ...

Imagine buildings in which the windows allow the sun's light to enter, and at the same time capture the energy from the sun needed to meet all their energy needs. In this seemingly futuristic scenario, the ...

Light is a slippery fellow. Stand in a darkened hallway and close a door to a lighted room: Light will sneak through any cracks—it doesn't want to be confined. "Typically, in free space, light will go everywhere," ...

(Phys.org)—A team of researchers with members from Hokkaido and Osaka Universities in Japan has used quantum entanglement of photons to improve image results created using differential interference contrast ...

Physicists Sergei Filippov (MIPT and Russian Quantum Center at Skolkovo) and Mario Ziman (Masaryk University in Brno, Czech Republic, and the Institute of Physics in Bratislava, Slovakia) have found a way ...

Scientists from the MESA+ Institute for Nanotechnology at the University of Twente in the Netherlands have designed a novel type of reso­nant cavity that serves as a prison for photons. The cavity confines ...
